Rome, February 6 - Centre-left leader Pier Luigi Bersani was warned on Wednesday not to consider making a post-election pact with outgoing Premier Mario Monti by coalition partner Nichi Vendola. Bersani and Monti, who is standing on a reform platform backed by centrist parties, made overtures to each other on Tuesday, with political pundits saying Bersani is likely to win the February 24-25 election but may not have a working majority in parliament. Vendola, the governor of Puglia and the leader of the left-wing SEL party, told Bersani that he and Monti were "incompatible". "I hope Bersani does not want to take the responsibility of breaking the centre-left alliance," added Vendola, whose party was staunchly opposed to Monti's emergency technocrat government unlike Bersani's Democratic Party, which supported it. "A vote for the SEL is an insurance policy for centre-left supporters. It's a guarantee that there won't be the heavy influence of Monti".
